Alessandro and Domenico Scarlatti

Most attributions are unreliable at best with cross references that go completely awry half way through, although a supreme effort is made to cover as many sources as possible. Many spelling mistakes (authors' names and musical terms); typographical errors occurring throughout the guide. In many cases, it would seem that the author used corrupted copies of source materials rather than available bound hard copy volumes and thus many attributions waste space pointing to artifacts that do not occur in the actual source.
